Abstract
An image forming apparatus including a driving source, a planetary gear mechanism including first, second and third elements, a rotation restraint member configured to switch the planetary gear mechanism between a locked state where rotation of the second element is locked and a released state where the second element is capable of rotating, and a switching mechanism configured to switch the planetary gear mechanism between a first state where any two elements of the first, second and third elements are separated and a second state where the two elements are coupled, wherein the third element is configured to rotate in a first direction when the planetary gear mechanism is in the locked state and first state and to rotate in a second direction opposite to the first direction when the planetary gear mechanism is in the released state and second state.
